Application filed August "I, 1907. Serial No. 387,478.

Be it known that I, RALEIGH W. Gonrnnr, a citizen of the United States,residing at Oberlin, in the county of Lorain and State. f Ohio, haveinvented new and useful Improvements in Gas-Engine Starters, of which ithe following is a s ecification.

This invention re ates to starters for gasolene and other explosiveengines; and it has for its object to providean 1m roved device wherebya suitable charge 0 gasolene or other motive fluid may be injected intothe Wit will readily appear as the nature of the invention is betterunderstood, the same consistsin the improved construction, and novelengine cylinder in a suitably heated condition and withan admixture ofatmospheric air, the mixture forming an explosive gas, ready tobeignited by the igniting mechanism of the engine.

Special -objects' of thepresent invention are to simplify and improvethe construction and o eration of this class of devices these and otherends in view which arrangement and combination of parts which Will'bBhereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention; it being, however, understood ithat no limitationis necessarily made to the recise structural details therein exhibited,ut that changes, alterations, and modifications within the scope of theclaims may be resorted to when desired.

In the'drawing: Figure 1 is a vertical sec tional view of the improvedstarter. Fig. 2 is an, endview of the same. I

Corresponding parts in both figures are denoted by -like characters ofreference.

The improved starter comprises a suitable cup or reservoir 1 having aconveniently detachable cap or cover 2 and provided with a measuringchamber 3 of elongated tubular form located adjacent to the bottomthereof and preferably extending diametrically across .said bottom; Thetube or barrel B which contains the measuring chamber isprovidedadjacent to the ends of the latter with valve casings 4' and 5, theformer of which commu 'nicates with the reservoir 1 through a port 6;

the casing 4' also communicates with the in: let end of the tube B throuh a port 7 and the casing 5 communicates wit the outlet end of the'tubeB through a port 8. The casings 4 and 5 are provided wlth ordinary twoway valves 9 and 10 which may be simultaneously turned to cut themeasuring chamber 3 off from the ends of the tube While said Incasuringchamber is at the same time placed in communication with the reservoir 1through the ort 6, this being the position illustrated in 1 y of thedrawings; it will be readily seen t .at by a quarter turn of the valves,the measuring chamber will be cut off from the reservoir, while theports connecting the measuring chambers with the ends of the tube orvalve will be thrown open. The

movement of the valves may be simultaneously effected by means of cranks11 suitably connected with the stems of the valves, and

connected with each other by means of a link 12 having a handle 13. Alug 14 extending downwardly from the barrel B carries a pan 15 in whicha small quantity of liquid fuel,

- such as-alcohol, may be placed and ignited for the *P 0 6 of heatingthe measuring? chamber an its contents.

The inlet end of the barrel B is threaded, as shown at 16, for thereception of a connecte ing pipe or duct whereby it maybe convenientlyconnected with a storage tank, not

communication with the reservoir 1 w ch latter may be filled by removingthe lid or shown, wherein atmospheric air is kept in cap 2. The contentsof the measuring chamber me be heated by igniting a small quan? tityofiquid fuel, such as alcohol, paced in the tank 15. The handle 13 isnow manipulated to partially rotate the valves 9 and 1 Q,

whereby the measuring chamber will be cut off from the reservoir 1, andthe contents of said measuring. chamber will be ejected by the currentof compressed air from the source of supply previously referred to. Thecontents of t e measuring chamber will first enter into the chamber or sace 17 and, with a free admixture of air, wi be forcibly projectedthrough the apertures 18 into the firing end of the engine cylinder;Being previously heated, the fluid will readily combine with the atmosheric'air to form an explosive mixture w ich will be ignited in theusual manner, thus starting the engine.

The improved deviceis simple in construc tion, and it has been found tobe thoroughly efficient for the purposes for which it is provided.

I claim:

1. A device of the class described comprising a reservoir, a tube orbarrel adjacent thereto and containing a measuring chamber communicatingwith the reservoir through a port or duct, and two way valves in thetube or barrel adjacent to the ends of the measuring chamber, one ofsaid valves being adapted to obstruct the port leading to the reservoir.1

2.. In a device of the class described, a reservoir, a tube containing achamber communicating with said reservoir, valves in the tube to cut oficommunication between the chamber and the ends of the tube, one of saidvalves being adapted to cut off communication between the chamber andthe reservoir, a compressed air chamber at one end of the tube and aperforated Wall at the opposite end of the tube.

3. In a device of the class described, a

reservoir, a tubular barrel extending diametrically across the bottom threof and having a chamber communicating therewith through a port orduct, valves or closures adjacent to the ends of the chamber, one ofsaid valves being adapted to obstruct the port leading to the reservoir,cranks connected with the valve stem, a link connected to said cranks,and a heating pan sup orted beneath the chamber in the tube or arrel.

4. In a device of the class described, a reservoir, a tubular barrelextending diametrically across the bottom thereof and having a chamberc'ommunicatin r therewith through a port or duct, valves a jacent to theends.

of the chamber, one of said valves being adapted to obstruct the ortleadin to the reservoir, a lug depending from the said tubular barreland arranged intermediate the ends thereof, a heatin pan connected tothe said lug, and a crank for effecting simultaneous movement of thevalves.

In testimony whereof I aflix my signature in presence of two witnesses.
